Biography

I am an MRC Career Development Research Fellow at the School of Infection and Immunity, University of Glasgow, where I lead research on the asexual blood-stage proliferation of malaria parasites. My lab develops and uses scalable, inducible gene knockout approaches to discover essential gene function in the most lethal human malaria parasite, Plasmodium falciparum.

Previously, I was a Marie Skłodowska-Curie Fellow in Prof. Mike Blackman’s lab at the Francis Crick Institute, London (2018-24) where I investigated the roles of several protein families - phospholipases, perforin-like proteins and rhomboid proteases - during the parasite's replication cycle within red blood cells. Before that, I conducted my doctoral research in the labs of Prof. Arnab Pain in King Abdullah University of Science and Technology, Saudi Arabia and Prof. Richard Culleton in Nagasaki Institute of Tropical Medicine, Japan (2012-17) where I established a genetic resource for an under-utilized rodent malaria model, Plasmodium vinckei.

 

Research interests

Malaria remains a devastating disease and a significant global health challenge. The blood stages of the malaria parasite are clinically important, as they are responsible for the symptomatic phase of the disease. To survive and propagate through its asexual life stages within red blood cells, the parasite relies on nearly half of its ~5000 protein-coding genes. However, the functions of many of these genes remain unknown. At the Parasite Functional Genetics Lab (ParaFuGe Lab), we aim to uncover the critical roles of these essential genes in the most lethal malaria parasite, Plasmodium falciparum.

To achieve this, we develop and employ scalable, inducible gene knockout approaches to study gene function. These tools enable us to systematically disrupt specific genes in the parasite at a desired point in time and generate multiple mutant lines. By studying these mutants using advanced -omics, biochemical, and imaging technologies, we aim to uncover the mechanisms of action of said genes to reveal new aspects of parasite biology.

Our current focus is on understanding the parasite’s asexual replication within red blood cells. During this stage, the parasite undergoes an extraordinary form of cell division called schizogony, where the parasite’s nucleus divides multiple times before the cell itself undergoes a form of cytokinesis, producing up to 24 daughter parasites. Many features of this process remain a mystery, including how the parasite initiates this phase and regulates its timing. We want to understand how such key decisions are taken and identify the molecules and mechanisms that are involved.

Supervision

In our lab, we use advanced genetic tools such as CRISPR-Cas9 and DiCre to precisely edit or knockout genes and routinely identify intriguing genes that could be investigated further to uncover their essential roles. With this as a starting point, we can shape projects around your interests and also offer support to help create strong proposals for independent fellowships. Feel free to contact me to discuss opportunities!
